BLAST+: architecture and applications.

TLDR
The new BLAST command-line applications, compared to the current BLAST tools, demonstrate substantial speed improvements for long queries as well as chromosome length database sequences.
Abstract
Sequence similarity searching is a very important bioinformatics task. While Basic Local Alignment Search Tool (BLAST) outperforms exact methods through its use of heuristics, the speed of the current BLAST software is suboptimal for very long queries or database sequences. There are also some shortcomings in the user-interface of the current command-line applications. We describe features and improvements of rewritten BLAST software and introduce new command-line applications. Long query sequences are broken into chunks for processing, in some cases leading to dramatically shorter run times. For long database sequences, it is possible to retrieve only the relevant parts of the sequence, reducing CPU time and memory usage for searches of short queries against databases of contigs or chromosomes. The program can now retrieve masking information for database sequences from the BLAST databases. A new modular software library can now access subject sequence data from arbitrary data sources. We introduce several new features, including strategy files that allow a user to save and reuse their favorite set of options. The strategy files can be uploaded to and downloaded from the NCBI BLAST web site. The new BLAST command-line applications, compared to the current BLAST tools, demonstrate substantial speed improvements for long queries as well as chromosome length database sequences. We have also improved the user interface of the command-line applications.

Functional Sites Induce Long-Range Evolutionary Constraints in Enzymes.

TL;DR: Observations show that functional sites, and in particular catalytic residues, induce long-range evolutionary constraints in enzymes, independent of known structural constraints on protein evolution such as residue packing or solvent accessibility.

Auxotrophy and intrapopulation complementary in the ‘interactome’ of a cultivated freshwater model community

TL;DR: The biology of some of the most common and yet‐uncultured bacteria in freshwater environments using a mixed culture from Lake Grosse Fuchskuhle is uncovered, highlighting the power of mixed cultures to extract naturally occurring ‘interactomes’ and to overcome inability to isolate and grow the microbes dominating in nature.

VRprofile: gene-cluster-detection-based profiling of virulence and antibiotic resistance traits encoded within genome sequences of pathogenic bacteria.

TL;DR: VRprofile has exhibited better performance for island‐like region predictions than the other widely used methods and might contribute to meet the increasing demands of re‐annotations of bacterial variable regions, and aid in the real‐time definitions of disease‐relevant gene clusters in pathogenic bacteria of interest.

A comparison across non-model animals suggests an optimal sequencing depth for de novo transcriptome assembly

TL;DR: These assembly trends suggest that representative assemblies are generated with as few as 20 million reads for tissue samples and 30 millionreads for whole-animals for RNA-level coverage, and beyond 60 million reads, the discovery of new genes is low and sequencing errors of highly-expressed genes are likely to accumulate.

Bioreactor microbial ecosystems for thiocyanate and cyanide degradation unravelled with genome-resolved metagenomics.

TL;DR: Genome-based metabolic predictions suggest that a large portion of each bioreactor community is autotrophic, relying not on molasses in reactor feed but using energy gained from oxidation of sulfur compounds produced during SCN(-) degradation.

BLAT—The BLAST-Like Alignment Tool

TL;DR: How BLAT was optimized is described, which is more accurate and 500 times faster than popular existing tools for mRNA/DNA alignments and 50 times faster for protein alignments at sensitivity settings typically used when comparing vertebrate sequences.

A greedy algorithm for aligning DNA sequences.

TL;DR: A new greedy alignment algorithm is introduced with particularly good performance and it is shown that it computes the same alignment as does a certain dynamic programming algorithm, while executing over 10 times faster on appropriate data.
